Therefore, ceramic insertion core will guarantee that in use light path is unimpeded, and loss of signal is little; On version, require connector right alignment height, smooth surface, pulling capacity is moderate, and is durable in use.As shown in Figure 1, be provided with the cylindrical shape ceramic insertion core main body 2 of through hole 4 in the middle of ceramic insertion core of the prior art is generally, though also can satisfy above-mentioned requirements, the interspersed installation inadequately of optical fiber makes things convenient for, and if faults such as fibercuts, maintenance is also convenient inadequately.
Summary of the invention
For solving the problems of the technologies described above, it is little that we have proposed a kind of optical coupling loss, connects accurate positioning, interspersed easy for installation, the stable performance of optical fiber, and can improve light signal transmission speed and middle fluting ceramic insertion core easy to maintenance greatly.
For achieving the above object, technical scheme of the present invention is as follows:
The fluting ceramic insertion core is installed in joints of optical fibre central authorities in the middle of a kind of, and the complexed metal seat uses, and described ceramic insertion core main body is cylindrical shape, is provided with a semi-cylindrical recesses in the middle of the described ceramic insertion core main body; Described ceramic insertion core modal length is 16 ± 0.05mm, and diameter is 1.599 ± 0.003mm; Described semi-cylindrical recesses length is 7.5 ± 0.05mm; Described ceramic insertion core main body axle center through-hole diameter is 0.126-0.127mm.
Preferably, through hole, axle center, described ceramic insertion core two ends is equipped with cone-shaped groove, and described cone-shaped groove diameter is 0.9 ± 0.05mm.
Preferably, handle at the rounded angle in described semi-cylindrical recesses and described ceramic insertion core main body angle.
Preferably, handle at the rounded angle of rounded edge, described ceramic insertion core two ends.
Pass through technique scheme, the present invention is by being provided with a semi-cylindrical recesses in the middle of the described ceramic insertion core main body, through hole, axle center, described ceramic insertion core two ends is equipped with cone-shaped groove, reach connection accurate positioning, interspersed easy for installation, the stable performance of optical fiber, and can improve the purpose of light signal transmission speed and convenient for maintaining greatly.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
The invention discloses a kind of middle fluting ceramic insertion core, this lock pin connects accurate positioning, interspersed easy for installation, the stable performance of optical fiber, and can improve light signal transmission speed and convenient for maintaining greatly.
Embodiment.
As shown in Figures 2 and 3, a kind of middle fluting ceramic insertion core is installed in joints of optical fibre central authorities, and complexed metal seat 1 uses, and described ceramic insertion core main body 2 is cylindrical shape, is provided with semi-cylindrical recesses 21 in the middle of the described ceramic insertion core main body 2; Described ceramic insertion core main body 2 length are 16 ± 0.05mm, and diameter is 1.599 ± 0.003mm; Described semi-cylindrical recesses 21 length are 7.5 ± 0.05mm; Described ceramic insertion core main body 2 axis through-holes 4 diameters are 0.126-0.127mm.Wherein, described ceramic insertion core main body 2 two ends axis through-holes 4 places are equipped with cone-shaped groove 5, and described cone-shaped groove 5 diameters are 0.9 ± 0.05mm; Be not scratched through semi-cylindrical recesses 21 places when optical fiber is assigned in through hole 4, described semi-cylindrical recesses 21 is handled with rounded angle, described ceramic insertion core main body 2 angles; Assign in metal pedestal 1 for the ease of ceramic insertion core main body 2, and simultaneously in order to make good looking appearance, handle at the rounded angle of described ceramic insertion core main body 2 two ends rounded edge.
